This paper summarizes the initial PALSAR calibration and validation results, which were being carried out after the first activation of the PALSAR image on Feb. 15 2006. The PALSAR calibration and validation consists of the sensor characterization, SAR processor tuning, and image quality evaluation. During the three month initial calibration phase and two month initial calibration phase, sensor characterization through the raw data evaluation for most of the sensor modes were conducted for interpretation of the performance. In this paper, we focus on the results that were gained during first 7 months after the ALOS launch. Although three months remained by the ALOS operation start, the report may cover almost of the PALSAR CAL/VAL.
